This pretty little Kundo 400 day clock is 8 7/16 inches tall without the dome. The ivory color base and pillars have flowers painted on them. It was made in the 1950s.

The movement is Horolovar back plate no. 1381, and I installed a 0.0024 inch thick Horolovar suspension spring (the 0.0023 inch springs I have now are slightly thinner than 0.0023 inch and make the clock lose time).

5. Miniature 400 Day Clock by Edgar Henn

This miniature 400 day clock is 8 1/4 inches tall without the dome. There in no name on the face. The back of the movement is labeled “Euramca”. The movement was made in Germany by Edgar Henn, and the “Horolovar 400 Day Clock Repair Guide” classifies this movement as plate 1088. It was made around 1953.

This clock uses suspension unit no. 29B, with a .0023 inch thick suspension spring. This clock ticks slower than the standard 400 day clocks, making only 7.5 beats per minute (8 beats in 64 seconds). Standard 400 day clocks by Kundo and Schatz make 8 beats per minute, and their miniature clocks make 10 beats per minute.

This video shows the remarkably large pendulum rotation on this clock, just over 1 1/2 turns when fully wound!

My parents gave me a 400 day clock for Christmas in 1968, when I was 13 years old. It is a Schatz miniature, dated 5 56 (May 1956) on the back, indicating that it is 13 months younger than I am. The clock came with a spare suspension unit, which I immediately installed, and the clock started working. The clock has been with me all these years. A few years ago, I took it apart for movement cleaning and bezel polishing, and a few days ago I polished and lacquered the outer part of the base to make it more photogenic. The separate base center cover has a nice patina so I left it alone. Thanks to this thoughtful gift from my parents, 400 day clocks are a favorite of mine, and a favorite part of my clock repair business is repairing these great clocks! (The red ring around the base is a reflection of the red background.)

I recently repaired this Kundo miniature 400 day clock with a pretty gold colored metal dial. The movement needed cleaning and a new suspension spring. The pivots and pivot holes were in good condition.

Here is a movie of the escapement in operation:

Here is a slide show showing the complete clock, and the gears in place before the back movement plate was put on:

This is a 1950′s Heco windup 400 day anniversary clock made by Kern & Sohne in Germany.

The height, including the glass dome, is 8 3/8 inches.

The base was polished and lacquered about 10 years ago. It still looks nice, but has a few small tarnish spots and a couple of dents (the worst dent is shown in the last photo below). The base also has a few small cracks.

This model of clock is the slowest ticking of the 400 day clocks. The pendulum makes one rotary swing each 10 seconds. The video below shows the clock in operation. This clock (like 99.99% of 400 day clocks) is time only and does not strike or chime.

Here is a close up movie of the escapement:

Suspension unit: 12C
